I placed two pictures about nanofood in my post to make the information more interesting and visual.
Why hello there my name is Makarios and I enjoy many past times. I enjoy TV and many American freedoms. My favorite sport is soccer. I fervently support a team from Italy called AC.Milian. Here is a picture of their best player Kaka.
Guess What’s for Dinner—Nanofood
The use of Nanotechnology in food can improve color, flavor and nutritional value of food. According to Nanoforum’s Nanotechnology in Agriculture and Food
if, “nanotechnology techniques or tools are used during cultivation, production, processing, or packaging of the food”, then the food is called nanofood. The US Food and Drug Administration says that one of the three things that
is “research, technology or products that focus on the atomic, molecular or macromolecular levels” (i.e. dimensions between 1-100 nanometers). Therefore, nanotechnology may be used to enhance food at the microscopic level in various ways. To put it in everyday terms, a
is about 100,000 nanometers wide!
The idea of nanotechnology in food sounds like something out of
, but it is not. Mayonnaise was created in 1765.
is actually made up of lipids (fats) and proteins that are apart of an
(the suspension of liquid within another liquid). The lipids and fats form tiny “droplets” that are the size of a few hundred nanometers. It is the interaction of the eggs, oil and water on a nanoscale that make makes it smooth and gives it a rich creamy taste.
What can nanofood mean for us? Scientists are working to create nanosized
that will contain vitamins, medicine, or coloring which can be released based on your needs or desires. When people think of a milkshake, they think of something that taste great but is very fattening. A Harvard University Physicist named
believes that nanotechnology can change that thought (
please look at the video on the site
). He has created something called colloidisome’s. Weitz says colloidisomes are “tiny capsules that are made of particles that are one tenth the size of a human cell and assemble themselves into a hallow shell.” Molecules of any substance can be placed inside this shell. The shell has microscopic holes that can allow the trapped molecule to be released. By adjusting the size and the density of the colloidsomes he can determine the time when the trapped molecules will escape from the shell. This is a type of time release technology. Weitz believes that fat blockers, medicine, and vitamins could be placed into the colloidsomes. So in the future, we could possibly eat a doughnut without absorbing the fat or take medicine by eating a candy bar.
In January of 2000, Kraft Foods established a consortium of research groups from 15 universities (13 in the United States and 2 abroad) to research the development of nanofood products that “
deliver what consumers want
.” Kraft believes that “interactive food” can be tailored to our specific needs and desires. For example, think of a drink that can be made to change to your favorite color, or a food that can recognize a person’s biological make up and the product would provide any nutrients that your body needs. For instance, if the person needs more calcium or iron then the nanofood would provide it. These deficiencies would be detected by nanosensors which would be ingested with food. Nanocapsules that contain the various nutrients would also be ingested, but remain inactive until triggered. Imagine being allergic to peanuts and eating a peanut butter cookie without the allergic reaction! (Note: In an email response to my post, Dr. Qingrong Huang, a nanotech research scientist at Rutgers University, explained that the nanofood consortium funded by Kraft Food, "lasted only a short time".)
According to the Woodrow Wilson International Center for Scholars, which publishes a nanotechnology database, currently there are four foods that are considered nanofoods. The following are two real examples of nanotechnology in food used today. Scientists from the Hebrew University of Jerusalem have developed a company called
. It uses nanocapsules to improve the delivery of nutrients to the body. Currently Canola cooking oil has a product called Canola Active which uses this technology. Canola Active oil is shown to lower cholesterol levels by 14 percent.
RBC Life Sciences
have created a dietary shake that eliminates the need for sugar. This is accomplished by adding pure cocoa into the nanoclusters. RBC has decided to call this technology cocoaclusters.
Although the promise of nanotechnology in food is exciting, there are some potential problems with nanotech foods. Nano particles are so small that they can enter any of your cells including your brain cells. Scientists do not know if these nano particles will have any effect in cells they were never intended to enter. “
I’d like to drink a glass of water and know that the contents will go into my stomach and not my lungs
” says Dr. Qasim Chaundry of the British government’s Science Laboratory. (Note: In an email response to my post, Dr. Qingrong Huang, of Rutgers University, confirmed that "safety" and "efficacy" issues are the "focus of current research". He also commented that the cost of producing nanofoods is a major concern.)
Nano Food Fun
The potential for nanotech food seems unlimited. Can you guess which food product uses nanotechnology? Post your answers on the blog.
Oh wow. Makarios, this is really awesome. - Erik
This is very good post Makarios. It has great length and it is very descriptive. Also you added creativeness by giving visual examples and you added a bit strip related to it. Also most of your links seem fine. Again very good post.
Can you find any other foods that use Nanotechnology?
Have you used any products that use Nanotechnology?
What new developments in nanotechnology do you think are possible?
What would you like to see as a nanofood?
Can you identify any problems with Nanotechnology?

My favorite lab was the cockroach lab. The premise was to act as if we were animal testers, and to see if cockroaches have preferences where they stand. My team observed that our cockroach preferred the female cockroach better than the empty space. This fits our hypothesis correctly. Here is a picture of a hissing cockroach.(I think Ms.Baker took it)
The wall gives cells rigidity and strength, offering protection against mechanical stress. In multicellular organisms, it permits the organism to build and hold its shape The cell wall also limits the entry of large molecules that may be toxic to the cell.
Most commonly found in plant cells
- Controls turgity
- Extracellular structure surrounding plasma membrane
- Primary cell wall: extremely elastic
- Secondary cell wall: forms around primary cell wall after growth is complete
